Evoke 2024 Seminar: Procedural Geometry on the Gpu by Mrvux

This seminar will explain various techniques to generate geometry on the fly using Gpu, which have been extensively used in (all) of our productions.
I will explain how we built our geometry modifier pipeline that allows us to build massive polygonal scenes every frame from simple geometry, giving details about constraints and how we overcome them eg : triangle/quadrilaterals faces, functional matching, host shader generation, polygon attributes, reducing amount of emitted primitives and combinatorial explosion.
I will show various pipeline stages used for that purpose (vertex/geometry/tesselation, and of course compute shaders), with all advantages and drawbacks for each of those.
To finish we will expose our current work on latest features that are currently in our list (mostly getting deterministic results, de-randomization and pseudo ordering)
Workshop will be using dx11/hlsl (and some c#), but can be easily translated to other pipelines (gl/vk).
